regulator: Handle deferred clk

[ Upstream commit 02bcba0b9f9da706d5bd1e8cbeb83493863e17b5 ]

devm_clk_get() can return -EPROBE_DEFER. So it is better to return the
error code from devm_clk_get(), instead of a hard coded -ENOENT.

This gives more opportunities to successfully probe the driver.

Fixes: ec662ba089da ("regulator: fixed: add possibility to enable by clock")
